PACKER.

Application filed March 15, 1924.

T aZZ lU/t0m 1t may concem:

Be it known that I, EDWIN E. GRADY, a eitizen of the United States of America end a resident of Cleveland, in the county of I Cuyahoga and State of Ohio, beve invented certain new and usetul Improvements in Packers, of which the following is a full, clear, end exact description.

In the packaging of material S11Cll as flour it is customary to utilize a packer which eomprises a long tube about Wliich the package 1s placed and within which is an impelling means usually in the form of a rotating screw or propeller arranged to torce tl1e material into the package end in addition to hold the material when the impeller ceases operation. Various attempts have been made to utilize such machines for packaging materials such as sand but it has been found tl1at while the machine wo-uld properly feed the material into the package tbe impelling means Was ineflective to stop tl1e flow o-f the material. My invention is designed to overcome tliis defect by providing; means for preventing the 110W of the material When the impelling means ceases op-- eration. In the drawings accompanying this specifieation end forming a part thereof I have shown, for purposes ot illustration, one forno which my invention may assume. In these drawings:

Figure 1 represents a vertical section through the tube showing this illustrative embodiment of my invention,

Figure 2 is a section on the line 2-2 of Figure 3, While Figure 3 is a section similar to Figure 2 but showing the parts arranged to permit passage of the material.

In the embodiment 0f n1 v invention berein shown I have utilized the usual tube 11, impeller shaft 12, and iinpellers 13, and have secured to the impeller shaft 12 a pair of disks 14: and 15 arranged to aocomplish the object of my invention.

The disk 14 is fixed to tbe shaft 12 for rotation therewith by means et :t pair of set screws 16 and is p-rovided with a plurality of apertures 17 separated by solid portions 18. The disk 15 is loosely mounted upon the shaft 12 betvveen the disk 141- and e col.- lar 19 secured to the sh2tft 12 by means of suitable set serews 20 and the disk 15 is provided with a plurality oi:' apertures 21 each of slightly less extent than the corresponding solid portion 18 of the disk 14 and Serial No. 699,544.

accordingly separated by solid portions 22 each 01: slightly greater extent than the apertures 17 01. the disk 14. Positioned on the disk 15 and extending into one of the apertures 17 01" the disk 14 is apiu 23 effective to cause the disk 15 to rotate with the disk 141 except for the lost motion pernuitted by the play et tbe pin 23 within tbe aperture 17 and an extension 24 thereof whioh is forrned of such width that the lost motion between the two disks is srdiicient to el1unge their relative position from that shown in Figure 2 in whieh tl1e solid portions of one disk exactly close the apertures in the other disk and that shown in Figure 3 in WhlCh the apertures are aligned to per- 1nit the passage of materia-l therethrough.

It Will be obvious rom tl1e ubove description that with the disks in the position shown in Figure 2 and with the impeller shaft 12 stationary the disks Will prevent passage of the material from the tube 11 that rotation of tlie impeller sl1aft 12 Will immediately rotate the disk 14 but Will not rotate the disk 15 until the pin 28 bus com pleted its travel aeross the aperture 17 and extension 24, that this lag in the rotation of the disk 15 Will. bring tl1e apertures 01 the two disks into alignrnent, that the disks Will maintain tl1is relative position until rotation 01 the shaf't 12 is terminated, that stoppage of the shaft 12 Will stop the disk 14 immediately but permit the disk 15 to rotate under its 0W11 inertiauntil the pin 23 l1astraversed the extension 24 and aperture 17 in the reverse direction, that in this position the apertures of one disk Will be opposed to the solid portions of the otber to prevent materia], passing from the tube 11, und that the disks Will rema-in in this relative position until the shaft 12 is again actuated.

In order to increase tbe certainty oi action of the disk 15 I prefer to forn1 the disk 15 of considerable thickness as herein shown and then to prevent the liklihood of material wedging between the disk 15 and the tube 11 I prefer to bevol the edge of' the disk 15 as shown ai; 25 4nd to prevent the liklihood of any materia] passing between the disks end tube 11 I prefer to seeur to the tube 11 a ring 26 overlying the peripl1- ery of the disk 14. In order to further increase the certainty of 210131011 01" the disk 15 I prefer to provide brake means (net shown) arranged to act upon the shaft 12 Wheu the pewer is diseonneeted fl0lll the shaft 12 so that the rotation of the shait 12 will cease abruptly. This brake means may be of auy suitable type suoli as e band encircling a drum on the shaft 12 and tensioned by the meehanism operating tl1e elutch connecting the sl1ait 12 to its drivng means. It Will be obvious to those skilled in the art that the particuiax' embodiment of my linve1ition l1erein deseribed end shown may be nuti0ushf modified without departiflg I treni the spirit of my invention 01 sacrificing the advantagesthereof and it Will there- Ifore be understoed that the disclosure herein is illustrativeonly end tlmt my invention is n0t limite d thereto.
